I am trying to load the contents of a cross-domain component from
another server, using dojo.io.iframe API; and I am getting the following
error:

Permission denied to access property 'getElementsByTagName'

I did everything as per examples on using dojo.io.iframe, and wrapped
the returned data in <textarea>, but I still get this error. Now it
looks like cross-domain issue, but isn't working with the cross-domain
security restrictions the very point of dojo.io.iframe?

The page makes the request, but then is unable to process it. I thought
this might have something to do with the CDN-loaded Dojo, but I tried
loading it locally, and got the same error. The one thing that seems to
be weird is that according to Firebug, blank.html never completes
loading, even though I can load it manually by copy-n-pasting the URL
into the browser just fine.

And dojo.io.script is the main way to get around cross-domain
restrictions. iframes still have them. If the source of an iframe is
a different domain from the rest of the page, the browser cuts off
access to the document.
